- Date Reported:
- 01 Oct 2020
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2020-25613.
- More information:
A potential HTTP request smuggling vulnerability in WEBrick was reported.
WEBrick (bundled along with jruby) was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to “smuggle” a request.
For Debian 9 stretch, this problem has been fixed in version 1.7.26-1+deb9u3.
We recommend that you upgrade your jruby packages.
